Pulses the LED when listening for voice commands.

I've followed the M5Stack documentation for using the buzzer but get no output. I found a Google thread that suggests the buzzer is actually connected to GPIO2 of the AXP192 PMIC and not GPIO2 of the ESP32 as the docs suggest.
Will add AXP192 support when I can and see if that is the case.
